Another thing to check is the front wishbones and drop links, know peeps have had replace these alot, mine creaked abit but new drop links sort it and ST200 front wishbones are pricey.

If it high mileage, check the water pump cos they start failing about 50K-60K and UIM/LIM of both ST24 and ST200 do soot up abit, but easily cleaned to give new lease of life.
